Specification of Letters Patent.

Patented Jan. 19, 1915.

To all whom it may concern.'

Be it known that we, Grenen E. DRUM, a citizen of the United States, and Jannes H. Snrr'r, a subject of the King of England, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Circulating Rotary Dyeing- Machines, of which the following is a speciiication.

The invention has for its object te provide means for circulating the dye liquor in the vat, and consequently through the goods, in two directions, whereby a more uniform dyeing of the goods is accomplished .than by those machines wherein the dye-liquor remains. in a quiescent state.

A further object is to provide means for operating the goods containing cylinder and the dye liquor circulating means in given directions during certain stages of the treatment of the goods and to reverse these directions of movements during alternate stages, the changes from forward to reverse directions of movements being effected either manually or automatically.

With these and other objects in view, reference will be had to the accompanying drawings forming a part of this specification and wherein like characters of reference designate corresponding parts throughout the several views, in which:

Figure l is a top plan view of the inven-` tion, parts of the gearing being omitted for clearness, Fig. 2 is a vertical sectional view therethrough on the line 2-2, Fig. 3 is a vertical sectional view through Fig. l on the line 3 3, Fig. l isa view in side elevation, with part of the gearing broken away in section, Fig. 5 is a view in vertical section through Fig. 4, Fig. 6 is a top plan View of the gearing, Fig. 7 is a view in elevation of Fig. 6 viewed from the left-hand side, Fig. S is a view in elevation of Fig. G viewed from the front side, and Fig. 9 is a view in elevation of Fig. 6, viewed from the righthand side. -V

The dye vat comprises two spaced parallel Vsides l connected by a round bottom 2, and within the sides are journaled the ends of the outer cylindrical wall 5 of the shaft 3 of the cylindrical goods container. The latter is constructed preferably of imperforate end walls 4, perforated outer cylindrical wall 5, and perforated radial partitions .6, 7, 8, 9, all regularly spaced and dividing the cylinder into four goods compartments A, B, C, D, for which latter suitable doors, such as the one 10 of Fig. l may be provided to permit the goot-.s to be put into and taken out of the several compartments. Between'the bottom 2 of the vat and the goods cylinder is provided a partition l2- extending from one side wall of the vat to the other. The lower end of this partition terminates at a point substantially adjacent an imaginary perpendicular line drawn through the of the cylinder. The lower portion of this partition 12 has substantially the saine curvature as the goods cylinder, and its upper portion verges from the outer wall 5 of the goods cylinder, its upper end terminating below an imaginary horizontal line drawn through the axis of the goods cylinder. TWhen the dye liquor is at its normal height in the vat, its level is substantially on a line with the axis of the goods cylinder, and between-the cylinder 5 and the upper right-hand side of the vat bottom, and, with its aXis substantially in this same liquid level line, is mounted a circulating paddle lil, the blades thereof, which may be of any suitable number, being attached suitably to a shaft l5. lllhen the goods cylinder and the circulating paddle operate in a forward direction, by means tobe later described, their directions of movement will be as indicated by the arrows E and F respectively, and the consequent circl'llation of the dye liquor will be in the directions of the arrows G and H, the arrows to be observed in Fig. 5. Upon reversal of the operating mechanism, these several respective directions of movement and of circulation are reversely to the directions indicatedby said arrows. In their operation, it will be observed that the paddle blades 14 barely clear the upper end of the partition l2, and thereby instead of the paddle being merely an agitator it forms is relatively straight and di-' with the partition a positive liquid propelling or pumping means incorporated in the vat structure. y

The gearing for accomplishing the above movements of the goods cylinder 5 and the circulating paddle, comprises a main shaft 2O and a reversing shaft 2l parallel therewith, both being suitably journaled in bearing brackets 22 and Q3 respectively on the plate 2l, and the said plate being suitably attached to one of the sides l of the vat. To the main or pulley shaft 2O is keyed the pulley 25 and pinionQt, and adjacent this pulley and close on the main shaft 2O is an intermediate pulley Q7. Beside this pulley 27 is another pulley 28 loose on the main shaft and keyed to a pinion 29 also loose on the main shaft, and on the inner end of the main shaft is keyed a pinion 30. To the reversing shaft 2l are keyed pinions 3l, 32, and 33, the first two being adjacent each other, and the larger one 8l meshing with pinion 26 of the main shaft. Intermediate the pinion 32 of the reverse shaft and the pinion 29 of the main shaft and in mesh therewith is a pinion Bil loose on a stud 35. To the paddle shaft l5 is keyed or otherwise affixed a pinion 36 which meshes with the pinion 30 of the main shaft. Gn the goods cylinder 5 is provided a gear ring 37 which meshes with the pinion 33 of the reversing shaft 2l. The power belt (not shown) when the machine is ruiming idle, runs on the intermediate free pulley 27, and for shifting it to the forward drive pulley Q5 or to the reverse drive pulley 2S, a shipper bar 3S with fork 39 is provided. The shipper bar 38 is endwise slidable in spaced supporting brackets l-O and ll and is provided with stops il?, and el?) for engagement with opposite sides of the bracket 1M). For locking the shipper bar in an intermediate position, a notch est is provided in the upper edgethereof and a detcnt l5 carried as an extension of a weight arm 46 enters into locking enva gement therewith. The weight arm il@ is pivoted at its lower end at a9 to the supporting bracket 40 and at its upper end carries a ball weight 50. To the handle of the shipper bar 25S is provided an upright arm which is connected by a horizontal link 53 with a crank arm fast on a rock-shaft 55, the latter being journaled in bearing fork 56 forming a` part of the bearing bracket To the opposite end of this rock-shaft is affixed a crank arm 57 having connection 57 with another crank arm 5S of a control rock-shaft-59, which latter' is suitably mounted on the side of the vat and extends within a point where its crank handle 60 may be conveniently grasped by an operator. Loose upon this shaft 55 is a pinion 6l meshing with a worm 61 on the reversing shaft 21, and the hub of the pinion 6l is provided with a lug 62,

which, Ias the pinionV 6l is moved one or the other by the operation of the reversing shaft engages with one or the other sides of a lug provided on a segmental weight arm (il to move the weight arm 64: up to and slightly over dead center, when the weight arm, being loose on the shaft 55, quickly falls by gravity to the completion of its movement in one or the other directions. This weight arm has an adiustable weight 65, and on its side opposite to the one bearing the lug G3 and at its front and rear ends are stop extensions 66 and 67, better illustrated in VFig. Between these stops 66 and 67 is confined a crank arm 68 y i fast on the rock shaft 55. The fall of the weight arm 6l by its gravity after passing over dead center causes one or the other of its stop extensions G6 or 67 to engage with the crank 68, thereby giving a quick throw to the latter, and thereby giving a similar quick rocking movement to the shaft 55, which movement is transmitted through the crankarm- 54, link 53 and upright arm to the shipper bar 3S. T he .result is a quick shipping of the belt from the pulley 25 to the pulley 28 or vice versa as the case may be, said movement under action of the weight arm being limited byV the said stops 42 and i3 on the shipper ar encountering the sides of the bracket Ll0. rThis shioping of the belt from pulley E25 to pulley Q7 results in automatic alternate forward and reverse rotation of the goods cylinder 5 and circulating paddle il, and when it is desired to stop the same to change the goods, the belt must be shipped manually by moving the shipper rod 38 either directly by hand or through the medium of the control shaft 59 to an intermediate position, where it may be locked by the operator throwing over the weight arm i6 to cause its detent Ll5 to engage in the notch le of the shipper bar. ln like manner, it will be seen that inasmuch as the shaft 55 is free from key with the pinion (il, it may be rocked manually through the medium of the side control shaft 59 to throw the shipper mechanism and consequently the belt so that the latter at any stage in the operation of the machine can be changed from one to the other of any of the three pulleys 25, and 28, It is vto be understood, of course, that the detent 45 in the normal operation of the machine unser automatic action is inrits disengaged position with respect to the shipper bar notch. ln the forwarc drive of the machine, the belt is shifted from the idle pulley 27 to the pulley 25, by means and in the manner already described, and motion is imparted therefrom through main shaft 2O and its keyed pinion 2G to the large pinion 3l of the reverse shaft 2l and through the rotation of said reverse shaft 2l to the pinion 33, which latter being in mesh with the cylinder gear ring 37 causes forward rotation of the goods cylinder 5 in the direction of the arrow E, Fig. 5. Meanwhile, they rotation of the main shaft 2O causes rotation of its pinion 30, which being in mesh with the paddle pinion 36, causes rotation of the paddle 14 in the direction of the arrow F, Fig. 5. 1n the reverse drive of the machine, the belt is shifted initially by manual means as already described from the idle pulley 27 to the reverse pulley 28, or subsequently to a forward driving stage from the forward drive pulley 25 to the reversing pulley 28 either manually or automatically through the means and in the manner already described. Motion is then imparted from the pulley 2S direct through its key to pinion 29 and therefrom through the intermediate pinion 34 to the pinion 32 of the reverse shaft 21. The consequent rotation of the reverse shaft 21 causes rotationof the pinion 88, which latter being in mesh with the cylinder gear ring 37 causes reverse rotation of the goods cylinder 5 reversely to the direction indicated by the arrow E, Fig.

5. Meanwhile, the rotation of thereverse.

shaft 21 causes rotation of the pinion 31 lreyed thereto, and this pinion 31 being in mesh with the pinion 26 which is keyed to the main shaft 20 causes reverse rotation of the main shaft 20 and corresponding rotation of the pinion 30 on the end thereof. The paddle wheel pinion 36 being in mesh with the pinion 30, the paddle is caused to rotate reversely to the direction of the arrow F, Fig. 5. Y

lThe operation of the apparatus, and the effect thereupon of the mechanism described, is as follows: The goods being in place in the cylinder 5, the cylinder and paddle are caused to rotate forwardly, that is, in the directions indicated by the arrows E and F respectively in Fig. 5. As the cylinder rotates, the dye liquor is circulated through its compartments successively substantially in the direction of the arrow H, in Fig. 5. The dye liquor as it clears the lower end of the partition 12 is drawn upwardly between said partition 12 and the vat bottom 2 by the paddle and is again forced over the upper end of the partition 12 back into the vat. This continues as long as the mechanism rotates forwardly, it being clear that the dye liquor passes through the goods in but a. single direction. Upon reversing the movements of the goods cylinder' and pad-- dle, the dye liquor is drawn reversely to the arrow H toward the paddle and then forced down the passage between the partition 12 and vat bottom 2 reversely to the arrow G. Clearing the lower end of the partition 12, the dye liquor'is again drawn over the partition to the paddle, thereby causing the goods in the cylinder 5 to be impregnated from their opposite sides from which they were formerly treated. This alternate foi'- ward and reverse operation of the mechanism with consequent forward and reverse circulation of the dye liquor results in flowing of the liquor through the goods from opposite sides in alternate stages, which is the present day advanced method of dyeing, and results in a very thorough and expedient saturation or dyeing of the goods, without wear and tear thereupon.

Importance is placed upon the curvature of the partition 12 conforming to the contour of the goods cylinder and being close thereto, there being no pockets in the partition between it and the cylinder where eddy currents or swirling of the dye liquor may set up to result in over or uneven dyeing of the goods adjacent the periphery of the goods container. Likewise, it is of importance that the goods cylinder or container be simultaneously reversible with the re,- versing of the circulation of the dye liquor. In apparatus where the circulation of the liquor reverses without corresponding reversal of the goods cylinder, the impregnation is more thorough during flow of the liquor in one direction than in the other for the reason that at one stage the liquor moves with the goods while at the other it moves contrary to the direction of movements of the goods. Hence, in one stage, the treatment is no better than a mere dipping of the goods, while in the other stage, the treatment amounts to an actual forcing of the liquor through the goods. 1n the present invention, both stages correspond in every respect.
